5. MIC GAIN: This cont ol is used to adjust, as equi ed, mic ophone input
sensitivity fo optimum amount of modulation in t ansmit. UNI DEN CORPO
RATION OF AM ERICA citizen's band t ansceive s hâve been designed to pe mit
the use to attain levels of modulation up to 100% depending on the setting of
the mic ophone gain cont ol, using the mic ophone p ovided with the unit.
UNIDEN's automatic comp ession and peak limiting ci cuits assu e maximum
modulation with minimum disto tion.
6. RF GAIN: This cont ol is used p ima ily to optimize éception in st ong signal
a eas. Gain is educed by counte clockwise otation of the cont ol.
7. CLARIFIER: The cla ifie cont ol is no mally set to the cente position. This
featu e has seve al uses and can g eatly enhance eceive ope ation. Fi st, if a
eceived signal is slightly off f equency, this cont ol can be ope ated as equi ed
to optimize the eceive f equency. The effectiveness of this cla ifie featu es
unde these conditions can be obse ved eithe by listening fo a mo e eadable
signal at the speake o by noting the S-mete eading when the cla ifie cont ol
is ope ated. Anothe effective application of this cont ol is in eliminating
adjacent channel inte fé ence f om st ong signais. Ope ate this cont ol, as
equi ed, to obtain minimum adjacent channel inte fé ence.
8. M ETER MODE SWITCH:
S/RF Position: Mete indicates elative t ansmitte output powe when t ansmit-
ing, input signal st ength when eceiving.
MOD Position: Mete indicates ave age pe centage of modulation.
9. NB/ANL SWITCH: When the switch is placed in the NB/ANL position, both of
RF Noise Blanke and Automatic Noise Limite ci cuits a e activated. The NB is
ve y effective fo épétitive impulse noise such as ignition noise. The ANL
educes most undesi able inte fé ence noises.
10. DIMMER SWITCH: This switch is used to adjust the b ightness of the LED
channel display and the mete . DIM position educes b ightness.
11. CH9 SWITCH: This switch is fo use when eme gency communication is needed
on the eme gency channel, CH9. P essing the CH9 switch activâtes CH9 ega d-
less of the position of the channel selecto switch. When CH9 switch is p essed,
the channel display is blanked and the CH9 indicato is activated.
12. M OD—S/RF METER: This mete displays elative t ansmitte RF output powe
and pe centage of modulation when t ansmitting, as well as input signal st ength
when eceiving. The mete is illuminated when powe is on, the illumination can
be adjusted by the DIMMER Switch fo optimum b ightness.
